Fractal array antennas are fractal geometry based structures for advanced wireless based applications. This book focuses on the generation of different fractal array antennas, such as linear, triangular, and rhombic fractal array antennas using concentric elliptical ring sub-array design methodology and application of fractal tapering techniques to rhombic fractal array antennas. This book exemplifies the generation process of fractal arrays and thinning techniques to reduce the complexity of these array antennas. This book is useful for the researchers those who want work on fractal array antennas owing to a brief literature survey of fractal arrays available in this book.
